Skip to content If you’ve built somewhere else, forget what you know. Los Angeles has one of the most complex, slowest, and most expensive permitting environments in the country.
This guide explains what permits you’ll need, how long they typically take, and what commonly slows things down — so you can plan realistically and avoid surprises.
Los Angeles County has over 80 incorporated cities, each with its own building department. Your jurisdiction depends on your property’s location:
First step: Verify your jurisdiction. The same street can have properties in different jurisdictions.
Not every project needs every permit. Here’s what typically applies:
|
Permit Type |
City of LA |
LA County |
Other Cities |
|---|---|---|---|
| Simple residential | 3–6 months | 2–4 months | 2–4 months |
| Complex residential | 6–12 months | 4–8 months | 4–8 months |
| Hillside projects | 8–14 months | 6–10 months | 6–10 months |
| High-fire zone | +1–3 months | +1–3 months | +1–2 months |
| Coastal zone | +3–12 months | +3–12 months | +3–12 months |
Expedited plan check: Available for a fee, but even expedited timelines are longer than standard timelines in most other cities. Expect to cut timeline by 30–50%, not 80%.
Before you compare bids, make sure every builder you’re considering meets these basics:
Reality check: First-time approval is rare in LA. Budget for 2–3 correction rounds minimum.
Reality check: First-time approval is rare in LA. Budget for 2–3 correction rounds minimum.
Properties in hillside areas face additional requirements:
Properties in fire zones must comply with Chapter 7A:
Timeline impact: Add 2–4 months to permitting for hillside compliance.
Fire department review: Separate plan check by Fire Prevention Bureau. Add 1–3 months.
After major wildfires (Eaton Fire, Palisades Fire), jurisdictions sometimes offer expedited pathways:
Reality: Even expedited fire-rebuild permits in LA take 4–8+ months. Plan accordingly.
We manage the entire permit process so you don’t have to:
Our experience with LA permitting means fewer correction rounds, faster responses, and fewer surprises.
No. Unpermitted work is a code violation, can result in stop-work orders, and creates problems when you sell. We never recommend starting without permits.
Permit fees in LA typically range from $20,000 to $100,000+ depending on project value and scope. Hillside, fire zone, and coastal projects are at the higher end.
Technically yes, but the complexity of LA’s process makes this very difficult for homeowners. Most owners hire a contractor or permit expediter.
Plan check has expiration limits. If you don’t respond within the allowed time, your application may be cancelled and you’ll have to start over.
We work primarily in City of LA and LA County, but we’re familiar with processes in Pasadena, Glendale, and other surrounding cities.
Every property is different. Let’s talk through your specific situation, identify the permits you’ll need, and give you a realistic timeline.
